To all-whom it'may concern Be it known that I, Fnenrzurcx E. Annou- QUIER, acit-izen of the United States, residin at Worcester, in the countv of Wor e ter one State of Massachusetts, have invented certain new and useful Im arovements in terial placed across the o ening and secured to the inner surface of the envelop; the prune obJect of my present invent-ion being to provide a convenient. practically efficient or anized mean as an attachment for en= ve op-Jnachines, and adapted for afiining transparent, strips or patches to the envelop hlank'swhile upon the upply pack or ele= vator plate at no front of the'machine; and

previous to the blanks being fed or trans erred to the gunnniug and folding appli= ances of the envelopdorniing machine.

A furtherobject is to provide a mecha= nism'of the-character describetladapted for attachment, are conveniently accessible position, pon tue front of an envelop -1na= chine of well known construction, and which while aflordlng tnea'nstor the manufacture of outlook envelops will not materially tertere with the manutacture of plain en= velops upon said machine.

+Anothe object is to provide an organised means f aut matically carrying the end of a con i s rip of trans arent material over the supply pack of enve op blanks rest-- ing upon the supporter or elevator platform, at the same time applying gum upon the en velop blank. severing a patch from the strip and simultaneously affixing the same to the topmost blank upon the pack. and means for transferring or feeding said patched blank I from the pack to mechanism for seal-gumming and folding said blank into envelop form. The nature. ObjQClfE and preferred embodiment of my invention are set forth and ex.

plained in the following detailed description. with reference to the accompanying drawings, the particular subject matter claimed being definitely expressed in the summary. I

In the accompanying drawings, Figure 1 represents a top plan view of mechanism embodying my invention, and showing itstrelotion as a plied to an envelop machine. Fig. 2 is a ront'elevatiou view of the same. Fig, 3 a back view ofthe mechanism looking in an opposite direction-to that of Fig. 2. Fig. at is a vertical section at line X X on Fig. 1. Figs. 5, 6 and 7 are detail "crosssectional views. showing the reciprocating carrier. vertically moving plunger, and pa per-gripping means at different positions of their action. Fig. 8 represents a longitudl nel vertical sectional view of the reciprocat mg carrier patch dcliv ery bed, and gumnung devices. Fig. 9 is a sectional view showing the plunger at position above the delivery bed. Fig. 10 is a cross-sectional view showing the gumap lying rolls. Fig, 11 i a se 'arat-e view of t e patch cutter .on the end o the-plan or. ii is a view of an envelop blank with a pa .ch thereon.

In the drawings only such portions of an envelop machine'are shown, as'will suflice for illustrating the relation of my improved, agghcafilggingattachment in respect to said inachine; since the structure of the envelop machine proper is not a part of my presentinvention; but it willbe understood that an envelop machine of any well known and itable construction is herein referred to for the purpose specified.

. At indicates thetable ant frame 0: such machine; B the po Mounted in or upon said guide-way is a re ciprocating carrier 12 having a vertically down upon the bed.

moving plunger 13 fitted therein. Tl. e lower end of said plunger is formed as a rectangular plate ll witha fiat under surface approximately conforming to the shape and size ot' the required transparent patch to be affixed. The sides of the carrier 12 are provided with flanges that fit the guide-way grooves and slide freely therein. The carrier connected by a rod 13 and pivotally attached link 13 to one arm of an angle lever 16 fulcrinned upon the stationary frame A. and having its: opposite arm actui a collar secured on the plunger. as indicated in Fig. 8. The plunger 13 is prevented from swinging out of alinement laterally, by a vertical pin 1.9 or equivalent guiding means engaging with the body of the carrier. lt'

' also provide upon the carrier 12. means for applying gum or adhesive substance to the envelop blank .at the same time that the patch is advanced to position to attachment thereon: said means being more fully hereinafter described.

Xumeral '20 indicates a patch-delivery bed. consisting of a stationary member having flat top surface occupying a position beneath that of the plunger-plate 1t when the latter is at the extreme end of its outward movement. as in Fig. 9. The patch material. or strip of transparent paper P. is drawn longitudinally across said bed from a supply roll of the same. mounted on an axis stud 21 fixed in a suitable bracket at the side of the machine. and within convenient reach. of the attendant. The sides of the bed 20 are preferably provided with upright or in-.

'tion means may be combined with the roll or strip P for giving tension thereon. or for preventing too rapid unw nding of the strip.

At one end of the plunger plate is there Any convenient fric-' is provided a transversely disposed perforating means. preferably comprising a thin steel plate T having a series of points or detents 8 along its lower edge. (see Fig. 11) adapted for partially severing the patchforming strip of transparent paper. as hereinafter described. Said detentcd plate is best attached to a reinforce bloc-l the ends oi which are fitted to freely slide up and down in grooves formed in longitudi nally projecting ears upon the plunger plate. The extent of independent movement of said perforator means. in relation to the plunger plate. is limited. by screws or studs 28 that pass through slots suitably formed througl said parts. The lower edge of the 'reintorce block 2T is formed squarefor adapted to serve as a clamping means against the end of the bed 20. for temporarily holding the strip Pas the patch severed therefrom. The perforator means is normally depressed by a suitable spring. or springs. 23}. the tension of hich is suilicient to press the perforating points into or through the patchsforming strip.

in connection with the plunger plate 11. ator near end opposite that on which the pertorator means islocated. I providea pair ofgrip members or nipper devices 2 for seizing the opposite edges of the patcht'orniing strip. and for drawing it forward over the envelop blank. Said nippers are preferably arranged as best illustrated in Figs, G and T. A nipper or jaw 12 ar'-.

ranged at each side of the plunger-plate:

anti each being of similar structure a de-' scription of one will equally apply to both. The nipper jaw 52 is fulcrumed upon the outer end of a swinging link 3 which has its inner end pivoted to the plunger plate. Said jaw has an inwardly otlset lip at its lower end. A. latch-burl pivoted to the jaw 3 below its fulcrum and adapted for alternate engagement at its inner upturned end with a pair of notches formed on a block 5 attached to the plunger-plate. A. spring is arranged to press downward upon the link 3. and a spring 6 is arranged to press upward on the latch-bar. substantially as indicated. The inwardly otiset lip servestor clamping the edge of the strip P against the under face of the plunger-plate. (see Fig. 5) and the outwardly ott'set lip serves for engaging with a lug or detent 9 attached to the guide-way bar 11 for retracting or releasing the grip of the nipper (see Fig. 6) when the patch is afiixed. When the nipper is at holding position the latch-bar r engages the inner notch and when the nipper is thrown oti the latch bar engages with the outer notch; thus retaining the nipper jaw in its latest position of adjustment until it is again shifted in theregular order of the operation. 1

Combined with the carrier 12 I provide an upwardly and downwardly movable frame 30 in the lower end of which are mounted gum-applying rolls 31 and 32; while in its upper part there is arranged a cross-bar having projecting ends with rollers 33 thereon that engage with guides 34 mounted upon the main guide-ways 11. (See Figs. 1, 8. 9 and 10.) The side bars of the frame 30 are preferably slotted and sup ported upon anti-frictional guiding rollers 35, the axes of which are fixed to the carrier so that the frame, with the gum-applying rolls, easily move in vertical direction. The guides 34, for controlling the vertical movement of the frame and gum-applying rollers are each formed with an inclined lug 36 and an overlying spring 3? arranged so that when the carrier moves forward the supporting rollers 33 travel along the top of the guides, thus keeping the gum-applying rolls elevated away from the envelop blank; but at the end of the guides they drop antl in returning to first position the supporting rollers 33 run under the guides 34;. thereby causing the gum-applying rolls to travel upon the blank for de positing gum thereon. until the supporting rollers runup the inclines 36 and pass to the upper level, raising the springs 37. which drops back to place in rear thereof. and lifting the gum-applying devices from contact with the blank. i

The gum-applying rolls 31 and 32 are each formed with three 'rinis which respectively place a line of gum upon the envelop blank. along the edgesand at the ends of the window openin The gum-roll 32 is made of small diameter. so that it can actclosely adjacent to the end of the plunger plate ll to apply gum to the blank at the extreme end ofthe window opening, or beyond the position that could be reached by a roll of larger diameter. such as the roll 31; while the latter roll is adapted for doing the principal. part of the gumming. The rolls 31 and 32 contact with each other and both with the surface of the blank. The

smaller roll receives its charge of gum from the larger roll 31. The bearing openings in the frame 30. for the journals of the gumapplying rolls. are made larger. up and down. than the diameter of the journals, so that the rolls are in a degree self-adjustable to any irregularities or unevenness at the top of the pack of blanks.

. 40 indicates an endless traveling belt mounted in alinement with the reciprocating carrier. upon pulleys l1 and 4:2 the axes of which are supported upon stationary portions of the machine: and 43 indicates a gum-distributing roll mounted in peripheral contact with said belt. The axles of the rolls :1 and l3 are operatively connected by spur gear's ll and are driven by gears T5 in connection with a rotary shaft or stud 46 Fig. 3) from the feed roll'shaft {9. or any; convenient part of the machine.

50 indicates a gum supply reservoir. hav; v ing nozzles or orifices from which gr m. or

adhesive substance can drip upon the roll l3,

which transfers it to the belt l0 and said belt in turn spreads itin'a thin film upon the faces of the applying roll 31. p

51 indicates a receptacle beneath the roll and belt for catching any gum that might drip therefrom. A scraper device 52 is provided for the gum-distributing roll l3. for regulating the film of gum applied to the belt.

5% indicates a rod orshaft supported by the housings or standards A and extending parallel to the carrier-guide-way ll. sonicwhat to the rearward thereof. and having mounted thereon two tappet levers or nit-1nbers 56 and 57 adapted to be swung down upon the plunger head for, (lel)lt lllg the plunger-plate ll; one of said tappet lev rs being positioned over the patch-deliverv bed and the other positioned over the blank supporting plate 10: and 59 indicates a rotatable cam-shaft turning in bearings on the end standards A? adjacent to the shaft 54. and having cams 60'and 1 mounted thereon and severally adapted for operating the respective tappet levers. See Figs. 1 and l.) The top of the plunger 13 is preferal'ily provided with a roll for receiving the contact of the tappetarms. i uitable springs are connected withthe tappct lever heads to keep them against their cams. The shaft 59 isoperated by gears 62 and the inclined shaft 63. which latter may be connected by a suitable train of gearing with the main shaft of the envelop machine. or by other approved power-applying means.

Mounted upon the shaft 59 there is a depending backwardly and forwardly swingin'g pick-up device 65. best shown in Figs. 3 and l. having a slottedbearing upon the shaft to permit up and down movement: and a tubular lower end connected by a pipe 67 with a suitable air exhausting means (not shown.) This pick-up device is joined by a pivotedly attached link 68 to the lower end of a lever 69 fulcrunied upon the shaft 5i. and actuated by a cam 70 mounted upon cam-shaft 59. A cam T1 is also arranged for moving the device 65- up and down. The function of this pick up device is to lift the edge of the patched envelop blank from the top fo'fthe pack E by suction. and to swing said-blank into the bite of the feeder-rolls T2 and T3 that feed it to the advancing or seal-gumming rolls D of the envelop machine. which take it on its way to the folding mechanism to be creased andfolded in. well known manner.

The upper feed roll T3. formed of two .short roll sections mounted to revolve upon -t-l1at receives its motion by a belt l7 "porting elevator of the envelop machine,

or its equivalent. An automatic regulating mechanism 7 8, controlled by a reciprocating rod and. evener device or feeler 79 acting against the top of the pack, is provided for keeping the upper surface of the pack at a given level for receiving the action of the patch-applying means.

To insure accurate registering of the plunger-plate 14: with the strip-delivering bed 20 and blank-supporting platform 10 at the respective limits of the reciprocative carrier movement, I provide the plunger plate with a projecting vertically grooved. member or lug 1' for engagement with registier-guards i and 0 attached to the carriersupporting guide-way 11, see Fig. 2. Said guards are formed with inwardly offset lower ends that engage the grooved member '1" only when the plunger is at partially depressed position; but leave the parts tree for endwise reciprocation while the plunger is in elevated position.

In the operation: Assuming that the gum- -.-t, devices are-charged with suitable adhesive material; that a rolled strip of transparent paper of the proper width is supportedv upon the stud 21; and that the end of mid strip is drawn over the bed 20 where it is temporarily retained by the air pressure. The r ciprocation of the carrier 12 moves the plvager-plate 14 and gum-applyrolls fronr the primary position (see Fig. 8) to a 'positiontFig. 9) where the plunger-plate 14 is over the bed 20. The tappet 57 is then actuated to press the plunger-plate down upon the delivery-bed and strip P, causing the perforator 'Z' to pierce the strip above the groove 23, while the'nippers 2- are caused to clamp the end of the strip against the plunger-plate. At the same time the roll-bearing frame 30 drops from the end. of its guide 34 letting the gum-applying rolls 31 and 32 (which have been carried to the farther end of the window opening) down to rest upon the surface of the topmost envelop-blank E. Then as the carrier moves toward its former position the gum-applying rolls travel along the surfaceof the blank, depositing the lines of gum thereon, and the patch-forming strip 3? is drawn forward by and with the plungerplate until the end portion thereof and plunger-plate are at. a position centrally over the opening in the envelop blank. The plunger is then forced down by the tappet and its actuating means, thereby causing the patch eneath the plunger-plate to be pressed down upon the gummed blank to which it adheres. Also. simultaneously with the downward movement. the reinforce block :27 clamps the strip P firmly against the end of the delivery bed 20 adjacent to the perforator plate 7. and the portion of said strip to form the patch is severed. torn or detached therefrom along the line of pertorations, and pressed upon the blank by the movement of the plunger. As the plungerplate descends, bringing the patch near the blank, the nippers 2 are released by their upper end contacting with the detents 9; and the latch bars l keep them distended while the plunger is raised to its primary position. The leading edge of the blank is then lifted by the pick-up device 65 and started on its way through the rolls for the seal-gumming and folding operations, leaving the top of the pack clear for repeating the operation of atiixin a patch, in like manner, to the next succeeding topmost blank on the pack.

After the patch is detached from the strip and the end of the latter released by the lifting of the block 27 therefrom, the strip is retained in position upon the bed until the plunger-p121 e again descends thereon, by air pressure. or the exhaustion of air, through the bed by any suitable well known apparatus.
